The first tunable diode laser analyzer designed specifically for process analysis

Process Laser Gas Analyzer The TruePeak Tunable Diode Laser (TDL) Gas Analyzer is designed for measurements in the most demanding processes. Measurements are made by sending a laser beam through the process at a specific wavelength that is absorbed only by the gas being measured. The result is a fast, non-contacting measurement under true process conditions.

Typical Applications

Combustion Analysis	Oxygen and CO measurement for process heaters, furnaces, incineration.
Process Oxygen Analysis	Reactor oxygen control
Safety Oxygen Analysis	Vent and flare headers. Reducing measurement error and reducing plant trips due to incorrect oxygen measurement
Trace Moisture in Aggressive Service	Part per million measurement in corrosive and polymerizing processes

Measurement Advantages

In Situ Analysis - For most measurements the TruePeak analyzer can be installed on the process. This improves Accuracy (measurement without changing the sample), Speed of response (no sample transport lag) and Cost of Ownership (elimination of costly sample conditioning and analyzer shelters).
Fast Response (1-20 seconds)
Interference Free for most applications - Unlike other technologies there are typically NO interferences such as paramagnetic offsets or electrochemical interferences.
Capable of Measurements with changing pressure/temperature/background gas - Other TDL analyzers can be affected by changes in the background gas composition and concentration. The TruePeak analyzer integrates the entire absorption peak to eliminate this error.
Process Pressures up to 20 Bar
Process Temperature up to 1500C
Aggressive Service - Common measurements are in processes with high particulate, corrosives, and high fouling conditions. This is possible since TDL is an Optical Measurement, no sensor contact with process.
Low LTCO (no moving parts, high MTBF for components) - With minimal or no sample transport and conditioning, no shelter required and no moving or consumable parts, cost of ownership is often 2-3x lower than alternate technologies.
